Least Common Multiple of 502/81,813/80,420/972

Given numbers are 502/81,813/80,420/972

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 502,813,420

Least Common Multiple of Numerators i.e. LCM of 502,813,420 is 28568820.

GCF of Denominators means GCF of 81,80,972 as per the given fractions.

GCF of 81,80,972 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 502,813,420

LCM of Fractions 502/81,813/80,420/972 is 28568820

2 502, 813, 420
3 251, 813, 210
251, 271, 70

∴ So the LCM of the given numbers is 2 x 3 x 251 x 271 x 70 = 28568820

Least Common Multiple of 502,813,420 with GCF Formula

Least Common Multiple of 502,813,420 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 502,813,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(502,813,420) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(502,813,420) x common factors =1 x 6 = 6

LCM(502,813,420) = ( 502 × 813 × 420 ) / 6

LCM(502,813,420) = 171412920 / 6

LCM(502,813,420) = 28568820


Lets's calculate GCF of 81,80,972

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 28568820/1

Therefore the LCM of Fractions 502/81,813/80,420/972 is 28568820
